The command "tlmgr info --only-installed" is used to retrieve information about the installed packages in the TeX Live distribution.
Here's a breakdown of each component of the command:
-
"tlmgr": This is the command-line interface for managing packages in the TeX Live distribution. It stands for "TeX Live package manager."
-
"info": This sub-command is used to retrieve information about the specified packages.
-
"--only-installed": This option tells tlmgr to provide information only for the packages that are currently installed on your system. It filters out any information about packages that are not installed.
When you run this command, it will display relevant information about the installed packages, such as the package name, version, and description. This can be useful when you want to get an overview of the packages installed on your TeX Live system.
